Andrew Purtell commented on HBASE-13516:
----------------------------------------
bq. Only needed in jdk8.
I think Stack meant not needed in jdk8 since perm gen went away and using these
options will cause the JVM to throw up warnings.
> Increase PermSize to 128MB

> Key: HBASE-13516
> URL: https://issues.apache.org/jira/browse/HBASE-13516
> Project: HBase
> Issue Type: Improvement
> Reporter: Enis Soztutar
> Assignee: Enis Soztutar
> Fix For: 2.0.0, 1.1.0
>
>
> HBase uses ~40MB, and with Phoenix we use ~56MB of Perm space out of 64MB by
> default. Every Filter and Coprocessor increases that.
> Running out of perm space triggers a stop the world full GC of the entire
> heap. We have seen this in misconfigured cluster.
> Should we default to {{-XX:PermSize=128m -XX:MaxPermSize=128m}} out of the
> box as a convenience for users?
